Income Taxes [Abstract]
Income Taxes	(7) Income Taxes The Company’s effective income tax rate was 16.4% for the three months ended March 31, 2020 and 31.7% for the three months ended March 31, 2019. The decrease in the effective income tax rate for the three months ended March 31, 2020 primarily reflects the favorable impact of the 2019 net operating loss (“NOL”), which is allowed to be carried back up to five years as a result of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), enacted on March 27, 2020. Under the CARES Act, the Company’s NOL generated in 2019 may be carried back to tax years when the federal statutory tax rate was 35% rather than the current rate of 21%, consequently generating a larger tax benefit from the NOL than that recognized prior to the enactment of the CARES Act. The favorable impact resulting from the enactment of the CARES Act was partially offset by the unfavorable impact of the vesting of restricted stock units for which a large portion of the share-based compensation expense recognized in prior periods will not be deductible for income tax purposes. The effective tax rate for the 2019 period was impacted by immaterial unfavorable nonrecurring items recognized during the period. In addition, the effective tax rates for both periods also reflect increases due to state income taxes and decreases due to impacts of earnings attributable to noncontrolling interests for which income taxes are not the responsibility of the Company.

(7) Income Taxes

The Company’s effective income tax rate was 16.4% for the three months ended March 31, 2020 and 31.7% for the three months ended March 31, 2019. The decrease in the effective income tax rate for the three months ended March 31, 2020 primarily reflects the favorable impact of the 2019 net operating loss (“NOL”), which is allowed to be carried back up to five years as a result of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), enacted on March 27, 2020. Under the CARES Act, the Company’s NOL generated in 2019 may be carried back to tax years when the federal statutory tax rate was 35% rather than the current rate of 21%, consequently generating a larger tax benefit from the NOL than that recognized prior to the enactment of the CARES Act. The favorable impact resulting from the enactment of the CARES Act was partially offset by the unfavorable impact of the vesting of restricted stock units for which a large portion of the share-based compensation expense recognized in prior periods will not be deductible for income tax purposes. The effective tax rate for the 2019 period was impacted by immaterial unfavorable nonrecurring items recognized during the period. In addition, the effective tax rates for both periods also reflect increases due to state income taxes and decreases due to impacts of earnings attributable to noncontrolling interests for which income taxes are not the responsibility of the Company.
